Description
Technical field
It is more particularly to a kind of to reclaim the integrated combustion gas heat of water for bathing waste heat using heat pump the present invention relates to field of energy-saving technology
The fuel gas water heating system that water installations discharge waste gas residual heat is reclaimed.
Background technology
With the increasingly raising of living standards of the people, application of the gas-operated thermal bath facility in family and hotel is more and more general
And.But there are problems that in use as follows：(1) be probably when needing to use hot water, in pipeline cold water or water temperature not
It is up to standard, tap discharge cold water is typically opened, untill output water temperature is up to standard, cause great lot of water resources waste；(2) need
It is simple long by the gas-operated thermal bath facility heat time when wanting hot water, cause the dual waste of water resource and combustion gas；(3) when having a bath,
Hot water is momentarily closed, after being then turned on hot water valve, there is cold water section or water temperature superheat section, comfort level is not high；(4) water for bathing exhaust temperature
At 30 DEG C or so, have surplus heat recycling value, but at present as direct discharging of waste water.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, it is integrated using heat pump recovery water for bathing waste heat the invention provides one kind
The fuel gas water heating system that gas-fired water heater discharge waste gas residual heat is reclaimed, can recycle temperature discharged cold water not up to standard, return
Receive water for bathing and combustion gas waste gas residual heat and can quickly supply hot water, meet demand of the user to hot water.
The technical solution adopted in the present invention is：
Fuel gas water heating system is provided with heat pump assembly, carries electric heating thermal insulation water tank, and can be set according to season or user's request
Fixed insulation and leaving water temperature, water storage tank volume can be designed according to user's request, and the hot water that can be provided separately at least 2 minutes is used
Amount；Water tank is equipped with water level monitoring and control system, and is linked with mixed water control valve, it is ensured that water storage tank water level is normal；
The main line of gas-fired water heater is connected with the hot water outlet of heat pump assembly by mixed water control valve, mixes water control valve
For monitoring gas-fired water heater leaving water temperature and heat pump assembly leaving water temperature, and by controlling water tank water outlet and gas and hot water
The mixed proportion of device water outlet is so that mixed water temperature reaches user's requirement；When water receiver output water temperature is up to standard, water control valve is mixed
Gas-fired water heater water outlet can be decreased or turned off, be only supplied water by heat pump assembly water outlet；
Water temperature being equipped with water terminal and detecting three-way magnetic valve and cold water loopback pipeline, three-way magnetic valve has measure water temperature work(
Energy；Terminal user needs hot water, and when water temperature is not up to standard in pipeline, three-way magnetic valve unidirectionally opens water tank loopback pipeline, and leads to
Subcooled water loopback pipeline is recycled to combustion gas heat economizer and is preheated, and reclaims combustion gas waste gas residual heat；Water temperature reaches in pipeline
Timestamp, three-way magnetic valve closes cold water loopback, unidirectional to open user's water outlet；
Enter heat pump recovery waste heat after being collected with water terminal drainage water for bathing, further the cold water temperature after lifting heating by the exhaust gases
Discharged after degree.
Compared with prior art, the beneficial effects of the invention are as follows：The present apparatus can save great lot of water resources after implementing, it is to avoid water
Temperature is not up to standard and waste, and can reclaim a large amount of waste heats, realizes energy-saving and emission-reduction；By adding mixed water control valve, can shorten
User waits the time used by gas heater heat hot water, improves comfort level.
Brief description of the drawings
Fig. 1 is to reclaim the gas and hot water that the integrated gas-fired water heater discharge waste gas residual heat of water for bathing waste heat is reclaimed using heat pump
System.
In figure, 1, gas-fired water heater, 2, combustion gas heat economizer, 3, heat pump assembly, 4, mixed water control valve, 5, three are powered
Magnet valve, 6, three-way magnetic valve, 7, three-way magnetic valve, 8, running water softening device.
Specific embodiment
The integrated gas-fired water heater of water for bathing waste heat is reclaimed with heat pump discharge the combustion gas heat that waste gas residual heat is reclaimed for hotel
Water system, considers, water storage tank volume can be set in 80-100L based on water consumption.
1. insulation heating water storage tank holding temperature can be set in 80 DEG C；
2. when being had a bath using hot water, it is assumed that now water temperature is 15 DEG C in water pipe, after opening hot water tap, three-way magnetic valve
5th, three-way magnetic valve 6, the conducting circulating chilled water of three-way magnetic valve 7, while mixed water control valve 4 is started working；
3. cold water mixes into heat pump water tank with 80 DEG C of hot water, because water is smaller (with the cold water for entering heat pump
Balance), water tank leaving water temperature is at 75 DEG C or so；
4. the regulation water mixing proportion of water control valve 4 is mixed, setting leaving water temperature is reached, while gas-fired water heater 1 is started working；
5. when gas heater leaving water temperature is gradually stepped up, mixed water control valve 4 automatically adjusts water mixing proportion, and hot water is progressively
There is provided by gas-fired water heater 1；
6. after collecting water for bathing and reaching uniform temperature and water, heat pump assembly 3 is started working and extracts heat；
7. when the leaving water temperature of heat pump assembly 3 is gradually stepped up, mixed water control valve 4 automatically adjusts water mixing proportion, and hot water is progressively
It is transitioned into and is provided by heat pump assembly 3.
For the ordinary skill in the art, teaching of the invention, do not depart from principle of the invention with
In the case of spirit, the changes, modifications that are carried out to implementation method, replace and modification still fall within protection scope of the present invention it
It is interior.
